Stackup Considerations

There is a lot to consider about the Layer Stackup when it comes to designing a manufacturable board. We’ll walk you through enabling symmetry, finding correct balance of your layers, materials, creating and loading templates, and adding a layer stack table for better communication between you and your manufacturer.

PCB Ground Plane Best Practices in Your Multilayer Stackup

Using a PCB ground plane in a stackup is the first step towards ensuring power and signal integrity, as well as keeping EMI low. However, there are some bad myths about ground planes that seem to persist, and I’ve seen highly experienced designers make some simple mistakes when defining grounds in their PCB layouts. If you’re interested in preventing excess emissions and ensuring signal integrity in your layout, follow these simple guidelines for implementing a PCB ground plane in your next board.

Using an LDO vs. Switching Regulator in Your PCB

As much as we’d like, the power we supply to electronics isn’t always stable. Real power sources contain noise, they might exhibit power instability, or they dropout unexpectedly. Thankfully, we have power regulators to help prevent some of these problems. For low power devices, we generally see two types of power regulators: a low dropout regulator (LDO) or a switching regulator. You can mix and match these at different points along your power bus, but there’s still the matter of choosing whether to use an LDO vs. a switching regulator in your designs.

Using Altium 365 for Sharing Simulations in the Cloud

Post-layout simulators for your PCB are very valuable tools. If you’re working through a complex design, it’s a good idea to put it through some level of simulation and analysis to evaluate the design before manufacturing. This is all easy with the cloud collaboration tools in Altium 365 and Ansys field solvers thanks to the EDB Exporter utility in Altium Designer. These existing tools in Altium Designer and any of the Ansys field solver utilities give you a simplified way to share design data, EDB files, and simulation results with anyone on your design team.

Microstrip Ground Clearance: How Close is Too Close?

If you take a look at any guidelines for controlled impedance traces, you’ll clearly see that the trace width is calculated without any ground pour near the trace. However, most designers will state that unused areas on each PCB layer should be filled in with grounded copper pour. If you bring some ground pour near a microstrip, you’ve now formed a coplanar waveguide arrangement. So now the question becomes, how much microstrip to ground clearance do you need to ensure you’ve hit your impedance goals?

PCB Layout Guidelines for Switching Power Supplies and Regulators

How to Combat Power Supply EMI in Your PCB

Power supplies are one of those systems we all tend to take for granted. Everyone’s first task in power supply design is usually to ensure the voltage and current output reach the desired level, probably followed by thermal considerations. However, due to safety issues, EMC requirements, the use of higher PWM frequencies, and the need for smaller packaging, power supply EMI should be a major design consideration. With that being said, what are the major sources of power supply EMI, and how can power supply designers keep them in check?

Why would they spend their time doing this? In this article, we’re going to review some of the free offerings that exist within the PCB design community. Once you’re armed with this information, you will spend most of your time designing and routing boards instead of pulling your hair out creating footprints all day.
